Bench Grinder Grinding Wheel Norton Clipper STARLINE 39C 150x20x32 Silicon Carbide 66253338042

Norton Clipper STARLINE 39C bench grinder grinding wheel, size 150x20x32 mm, is a silicon carbide (SiC) abrasive wheel engineered for bench and pedestal grinders. It is designed to grind, deburr and shape hard, brittle and non-ferrous materials where a hard abrasive grain is required. The wheel dimensions 150 x 20 x 32 mm fit common bench grinder flanges and provide a stable working surface for consistent material removal and edge preparation.

Advantages

The silicon carbide composition offers high cutting efficiency on hard and brittle substrates and delivers a sharp abrasive action for rapid stock removal. The wheel's balanced construction reduces vibration during operation, improving comfort and surface finish. Its standard 32 mm bore and nominal width provide compatibility with many bench and pedestal grinders while enabling controlled grinding pressure and predictable wear characteristics.

Suitable for

• Grinding and shaping of cast iron and hard non-ferrous metals
• Tool sharpening and shaping of cutting edges
• Deburring of brittle parts and finishing of surface irregularities
• Preparation of surfaces before welding or coating

Key specifications

• Abrasive material: Silicon carbide (SiC)
• Diameter: 150 mm
• Width: 20 mm
• Bore diameter: 32 mm
• Type: Bench/pedestal grinder wheel for hard and brittle materials

How to use

Mount the grinding wheel on a compatible bench or pedestal grinder following the machine manufacturer's mounting instructions and safety requirements. Ensure the wheel is properly dressed and balanced before use. Operate the grinder at the rated speed and apply steady, moderate pressure to the workpiece; avoid excessive force that can cause overheating or wheel damage. Use appropriate coolant or intermittent contact where recommended for the material being worked to extend wheel life and maintain finish quality.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask. Check the wheel for cracks or damage before each use, and perform a ring test if applicable. Match wheel grain hardness and grit to the specific task: finer grits for finishing and coarser grits for rapid stock removal. Ensure wheel guards and spark shields are in place and that work rests are adjusted close to the wheel surface for safe operation.
